Abstract:
Charcot-Marie-Tooth (CMT) disease is a genetically heterogeneous group of disorders. Pain is a less common symptom complained by CMT patients. We described a case of a 39-year-old male patient affect by Charcot-Marie-Tooth (CMT) disease compared to five healthy controls (HC), to assess the sensory and the nociceptive pathways by using LEPs recording associated to fMRI examination, to find an "objective" marker which could be used in the management of CMT patient. The nociceptive system was evaluated by laser-evoked potentials (LEPs). Moreover, fMRI (functional magnetic resonance imaging) examination, by using laser stimuli, was performed. LEPs' examination showed an increase of latency and an amplitude reduction respect to HC. The laser stimulation during fMRI showed a decreased cortical activations if compared to HC. The originality of this paper, although limited to a single case, resides in a detailed evaluation of CMT1 patient performed by using neurophysiologic and neuroimaging methods to investigate extensively the sensory nociceptive pathways.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:
Potential Energy
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...
Standard Electrode Potentials
Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
